Description

Technical Field

[0001] This utility model relates to the field of pile planting technology, and in particular to a pile frame for pile planting. Background Technology

[0002] A pile driver is a mechanical device used in foundation engineering construction, primarily for driving various types of piles (such as concrete piles and steel piles) into the ground. Before driving a pile, a drill rod needs to be used to drill a hole of a predetermined size and depth into the ground, after which the pile body can be inserted into the hole. Since the length of the drill rod is limited, when the required drilling depth exceeds the length of a single drill rod, multiple drill rods need to be joined together for drilling.

[0003] However, because the drilling rig is located at a high position, the drill rods to be spliced ​​cannot be stored at the same height as the rig and are usually laid horizontally on the ground. Similarly, precast piles also need to be laid horizontally on the ground before being installed, and are only hoisted onto the pile-planting machine during the installation process. Therefore, when new drill rods or piles need to be spliced ​​or installed, a crane is required to lift the drill rods or precast piles laid horizontally on the ground. Furthermore, to avoid operational interference, existing pile-planting machines complete the drilling operation first before lifting the horizontally laid precast piles from the ground, resulting in a slow construction pace. This undoubtedly wastes a significant amount of time and labor costs. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a pile frame for planting piles, so as to solve the problem of low construction efficiency caused by the need to lift drill rods and precast piles during construction in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pile frame for planting piles, including a walking chassis and a guide frame that is erected on the walking chassis and can rotate.

[0006] The walking chassis is provided with a pile storage cylinder for storing precast piles near the bottom of the guide frame. The guide frame is arranged with at least one drilling component mounting part for installing drilling components and at least one pile planting component mounting part for installing pile planting components along the circumferential direction of rotation.

[0007] The guide frame is equipped with a drill rod gripper near the mounting portion of the drilling component. Further, the drilling component is used to connect a first drill rod; the drill rod gripper is used to grip a second drill rod.

[0008] The drill pipe gripper includes a clamping arm rotatably mounted on the guide frame. The clamping arm can be deflected relative to the guide frame to move the second drill pipe to a position concentric with the first drill pipe. The second drill pipe is detachably connected to the first drill pipe.

[0009] Furthermore, the drill pipe gripper includes at least two gripping arms, and the two gripping arms are at different heights;

[0010] The clamping arm includes: a first clamping block, one end of which is hinged to the guide frame, and the other end of which has a first clamping surface for contacting the second drill pipe; and a second clamping block, which is hinged to the first clamping block, and the second clamping block has a second clamping surface for contacting the second drill pipe.

[0011] Furthermore, the drill pipe gripper also includes: a first telescopic member, one end of which is hinged to the guide frame and the other end of which is hinged to the first clamping block; and a second telescopic member, one end of which is hinged to the first clamping block and the other end of which is hinged to the second clamping block.

[0012] Furthermore, the pile storage cylinder includes a constraint section, which is cylindrical in shape, and the inner wall of the constraint section can abut against the outer peripheral wall of the precast pile.

[0013] Furthermore, the storage cylinder also includes a guide section, which is fixed to the upper end of the constraint section. The guide section is frustum-shaped and its diameter gradually decreases from top to bottom.

[0014] Furthermore, the traveling chassis includes a piling machine platform and a traveling mechanism located at the bottom of the piling machine platform; the pile storage cylinder is disposed on the piling machine platform.

[0015] Furthermore, it also includes:

[0016] A crane is installed on the pile driver platform, and the crane boom is equipped with a hook that can lift the precast pile.

[0017] Furthermore, it also includes:

[0018] The first clamping and pressing pile planting mechanism is located in the middle of the pile driver platform and can move between the crane and the guide frame;

[0019] And / or, a second clamping and stake planting mechanism is provided on the side of the walking chassis near the guide frame.

[0020] Furthermore, the pile-planting component includes a pile-clamping hand, which includes at least two pile-clamping arms that can move away from or close to each other to release or clamp the precast pile.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] By adding a pile storage cylinder to store precast piles, the precast piles can be directly grabbed from the storage cylinder during pile planting. A drill rod clamp is added to hold the drill rods; when multiple drill rods need to be spliced, they can simply be grabbed by the clamp and connected to the existing drill rods. During construction, there is no need to lift new drill rods and precast piles from the ground, improving the efficiency of splicing drill rods and lifting precast piles during drilling, optimizing the construction cycle, and increasing construction efficiency.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] Please refer to Figures 1-3 This utility model discloses a planting stake frame, including a walking chassis 200 and a guide frame 100 that is erected on the walking chassis 200 and can rotate.

[0031] The chassis 200 is provided with a pile storage cylinder 220 for storing precast piles near the bottom of the guide frame 100. The guide frame 100 is arranged circumferentially with at least one drilling component mounting part for installing drilling components and at least one pile planting component mounting part for installing pile planting components. The drilling component mounting part refers to a guide rail that allows the drilling component to slide up and down, or may also include a moving part that can drive the drilling component to move up and down. The pile planting component mounting part refers to a guide rail that allows the pile planting component to slide up and down, or may also include a moving part that can drive the pile planting component to move up and down. The pile planting component refers to a component that can drive the precast pile to be planted.

[0032] The guide frame 100 is equipped with a drill rod gripper 110 near the drilling component mounting section. Specifically, the drill rod (second drill rod) can be pre-lifted from the ground by the crane 210. When multiple drill rods need to be spliced, the drilling component is first separated from the current drill rod (first drill rod). Then, the guide frame 100 is rotated to make the drilling component deviate from the first drill rod. Next, the clamping arm is rotated to clamp the second drill rod and move it to be concentric with the first drill rod, splicing the two drill rods. Finally, the guide frame 100 is rotated to move the drilling component to the top of the two drill rods and connect them, so that drilling can continue.

[0033] Meanwhile, precast piles can be stored in the pile storage cylinder 220 in advance. When it is necessary to install the piles, they can be picked up from the pile storage cylinder 220. When the drilling components are drilling, the crane 210 can lift the precast piles from the ground in advance and temporarily store them in the pile storage cylinder 220, saving the time of hoisting the precast piles and improving the construction efficiency.

[0034] Therefore, this project adds a pile storage cylinder 220 to store precast piles. During pile installation, the precast piles can be directly grabbed from the storage cylinder 220 without hoisting. A drill rod gripper 110 is added to hold the drill rods. When multiple drill rods need to be spliced, the drill rod gripper 110 simply grabs and connects the drill rods to the existing drill rods. During construction, there is no need to lift new drill rods and precast piles from the ground, which improves the efficiency of splicing drill rods during drilling and shortens downtime.

[0035] Furthermore, the drilling component is used to connect the first drill rod and drive the first drill rod to drill a hole; the drill rod gripper 110 is used to grip the second drill rod;

[0036] The drill pipe gripper 110 includes a clamping arm rotatably mounted on the guide frame 100. The clamping arm can be deflected relative to the guide frame 100 to move the second drill pipe to a position concentric with the first drill pipe. The second drill pipe is detachably connected to the first drill pipe.

[0037] Furthermore, the drill pipe gripper 110 includes at least two gripping arms, and the two gripping arms are at different heights;

[0038] The clamping arm includes: a first clamping block 111, one end of which is hinged to the guide frame 100, and the other end of which has a first clamping surface for contacting the second drill rod; and a second clamping block 112, which is hinged to the first clamping block 111, and the second clamping block 112 has a second clamping surface for contacting the second drill rod.

[0039] Specifically, the first clamping surface on the first clamping block 111 is arc-shaped, and the second clamping surface on the second clamping block 112 is arc-shaped. The first clamping surface and the second clamping surface can be located on both sides of the second drill rod. When the first clamping surface and the second clamping surface are close to each other, the first clamping surface and the second clamping surface abut against the opposite side of the peripheral wall of the second drill rod to clamp the second drill rod. When the first clamping surface and the second clamping surface are far apart from each other, the first clamping surface and the second clamping surface can be separated from the peripheral wall of the second drill rod to release the second drill rod.

[0040] Furthermore, the drill pipe gripper 110 also includes: a first telescopic member 113, one end of which is hinged to the guide frame 100 and the other end of which is hinged to the first clamping block 111; and a second telescopic member 114, one end of which is hinged to the first clamping block 111 and the other end of which is hinged to the second clamping block 112.

[0041] Specifically, the extension and retraction of the first telescopic member 113 causes the first clamping block 111 and the second clamping block 112 to rotate relative to the guide frame 100; the extension and retraction of the second telescopic member 114 causes the second clamping block 112 to rotate relative to the first clamping block 111, thereby causing the second clamping surface to move towards or away from the first clamping surface, thus achieving the clamping or release of the second drill rod. The first telescopic member 113 and the second telescopic member 114 are hydraulic cylinders or pneumatic cylinders.

[0042] Furthermore, the pile storage cylinder 220 includes a constraint section, which is cylindrical in shape, and the inner wall of the constraint section can abut against the outer peripheral wall of the precast pile.

[0043] Furthermore, the storage cylinder 220 also includes a guide section 221, which is fixed to the upper end of the constraint section. The guide section 221 is frustum-shaped and its diameter gradually decreases from top to bottom.

[0044] By setting the guide section 221, it is possible to reduce the difficulty of inserting the precast pile into the storage cylinder without completely aligning it with the cylinder, as only approximate alignment is required. Specifically, after the lower end of the precast pile contacts the guide section 221, as the precast pile gradually descends, it can slide along the inner wall of the guide section 221 until it slides into the restraint section.

[0045] Furthermore, the traveling chassis 200 includes a piling machine platform and a traveling mechanism located at the bottom of the piling machine platform; the pile storage cylinder 220 is disposed on the piling machine platform.

[0046] Furthermore, it also includes:

[0047] Crane 210 is mounted on the pile driver platform, and the boom of crane 210 is equipped with a hook for lifting the precast pile.

[0048] Furthermore, it also includes:

[0049] The first pressing and planting mechanism 230 is located in the middle of the pile driver platform and can move between the crane 210 and the guide frame 100 to apply a downward force to the precast pile.

[0050] And / or, a second clamping and planting mechanism 130 is provided on the side of the walking chassis 200 near the guide frame 100.

[0051] Specifically, after drilling, the precast pile is placed into the hole and lowered to a predetermined depth by its own weight. If the precast pile cannot be lowered by its own weight, the first pressing and planting mechanism 230 can apply a downward force to the precast pile to assist in the planting.

[0052] Furthermore, the pile planting component includes a pile clamping hand 120, which includes at least two pile clamping arms that can move away from or close to each other to release or clamp the precast pile.

[0053] In this case, if non-edge piles are installed, the construction process is as follows:

[0054] 1. The entire equipment travels to the pile position via the walking chassis 200, and lowers the walking boat plate (set at both ends of the walking chassis 200 to stabilize the vehicle body), so that the walking chassis 200 and the walking boat plate make stable contact with the ground.

[0055] 2. Drilling is carried out through the drilling component suspended on the guide frame 100. After the first drill rod is drilled, the drilling component is separated from the drill rod that has been drilled into the ground, and the guide frame 100 is rotated so that the drilling component and the drill rod are deviated from each other and are not on the same center.

[0056] 3. Rotate the drill rod gripper 110 holding the drill rod to the position of the drill rod that is drilled underground, and make the drill rod that is drilled underground concentric with the drill rod to be spliced. Then splice the lower end of the drill rod with splicing to the upper end of the drill rod that is drilled underground, and then release the drill rod.

[0057] 3. Rotate the guide frame 100 to bring the drilling component back above the drill rod. After connecting with the drill rod, continue drilling. Repeat steps 2 and 3 until the designed depth is reached.

[0058] 4. After enlarging the hole and grouting, pull the upper drill rod out of the ground, disassemble the drilling components and the drill rod, and use the drill rod gripper 110 to hold the disassembled drill rod. Separate the lower end of the disassembled drill rod from the drill rod below the ground, rotate the drill rod gripper 110 to place the disassembled drill rod on one side, and repeat the previous steps until the drill rod is completely pulled out.

[0059] 5. Rotate the guide frame 100 to make the drill bit and drill rod deviate from the drilling position, and move the first clamping and planting mechanism 230 so that the center of the first clamping and planting mechanism 230 is located at the center of the drilling hole.

[0060] 6. The precast pile is lifted by a crane arm and placed at the center of the borehole for self-weight pile driving. When welding or other methods of pile splicing are required, the first clamping pile driving mechanism 230 applies downward pressure until the pile is driven into the elevation.

[0061] In this case, if edge piles are installed, the construction process is as follows:

[0062] 1. The entire equipment travels to the pile position via the walking chassis 200, and lowers the walking boat plate (set at both ends of the walking chassis 200 to stabilize the vehicle body), so that the walking chassis 200 and the walking boat plate make stable contact with the ground.

[0063] 2. Rotate the guide frame 100 to make the drill rod concentric with the second clamping and planting mechanism 130, and drill through the drilling component suspended on the guide frame 100. After the first drill rod is drilled, separate the drilling component from the drill rod that has been drilled into the ground, and rotate the guide frame 100 so that the drilling component and the drill rod are deflected and not on the same center.

[0064] 3. Rotate the drill rod gripper 110 holding the drill rod to the position of the drill rod that is drilled underground, and make the drill rod that is drilled underground concentric with the drill rod to be spliced. Splice the lower end of the drill rod with splicing to the upper end of the drill rod that is drilled underground, and then release the drill rod.

[0065] 3. Rotate the guide frame 100 to bring the drilling component back above the drill rod. After connecting with the drill rod, continue drilling. Repeat steps 2 and 3 until the design elevation is reached.

[0066] 4. After enlarging the hole and grouting, pull the upper drill rod out of the ground, disassemble the drilling components and the drill rod, and use the drill rod gripper 110 to hold the disassembled drill rod. Separate the lower end of the disassembled drill rod from the drill rod below the ground, rotate the drill rod gripper 110 to place the disassembled drill rod on one side, and repeat the previous steps until the drill rod is completely pulled out.

[0067] 5. The lifting boom places the precast pile to be implanted into the pile storage cylinder;

[0068] 6. Rotate the guide frame 100 so that the hook on the guide frame 100 can lift the precast pile and clamp the precast pile with the pile clamping hand 120;

[0069] 7. Rotate the guide frame 100 to make the precast pile and the second clamping and planting mechanism 130 concentric, release the pile clamping hand 120, and lower the hook holding the precast pile into the second clamping and planting mechanism 130.

[0070] 8. The hook holding the precast pile moves downward to plant the pile. When the top of the pile is close to the second clamping pile planting mechanism 130, the second clamping pile planting mechanism 130 clamps the precast pile. Repeat steps 5-7, place the upper pile section on the top of the pile joint that has been planted in the hole for connection, and then continue to plant until the design elevation is reached.
